A comprehensive lesson on multiplication facts 1-12 using arrays and skip counting strategies, styled as architectural blueprints.

A comprehensive lesson focused on identifying, naming, and comparing fractions using visual models, number lines, and real-world applications. Students move from basic identification to complex comparisons of fractional parts.

A comprehensive introduction to simplifying fractions using a 'Shrink-O-Matic' lab theme. Students learn to identify common factors and divide to reach the simplest form through differentiated practice and visual models.

An introductory lesson on fractions for 3rd grade, focusing on equal parts, naming fractions, and visual representations using circles and rectangles. Students act as 'Factory Inspectors' to ensure all parts are equal and correctly labeled.

A cross-curricular lesson for 1st-3rd graders that combines basic rhythm notation with addition and subtraction. Students decode musical patterns to solve "math mysteries" and perform rhythms.

A hands-on lesson where students measure various 'specimens' to the nearest half-inch and organize their data into a line plot to identify patterns.

A lesson focused on mental math strategies for double-digit addition, specifically exploring how to maintain a sum while changing addends (conservation) and how to efficiently add increments of tens and ones.

Compose new shapes from smaller shapes and decompose larger shapes into smaller ones.

Identify and distinguish 3D shapes (cubes, cones, cylinders, spheres) and find them in the real world.

Identify and describe 2D shapes (circles, triangles, squares, rectangles) by their sides and vertices.

A 3rd-grade math expedition where students solve 2-step addition and subtraction word problems using a 5-step safari protocol: Jungle Scan, Expedition Goal, Scout the Trail, Mapping the Model, and Final Report.

Final mastery check of AZ 3.G.A.2 skills: partitioning shapes, identifying unit fractions, and explaining the relationship between parts and the whole area.

Students explore how the same shape can be partitioned into equal areas in multiple ways, reinforcing that fractional parts must have equal area but not necessarily identical shapes.

Students partition circles, rectangles, and squares into 2, 3, 4, 6, and 8 equal parts with precision, meeting the partitioning requirements of the AZ standards.

Students express the area of one part as a unit fraction (1/b) of the whole, connecting partitioning to numerical notation as required by AZ 3.G.A.2.

Students define equal shares and identify them in circles and quadrilaterals, establishing the foundation for AZ 3.G.A.2 by distinguishing area from shape.

A final review and assessment of all skills learned throughout the Fraction Factory unit.

Exploring different ways to partition the same shape into equal areas, reinforcing that shapes can look different but have the same fractional area.

Practicing partitioning circles, rectangles, and squares into specific numbers of equal parts (2, 3, 4, 6, 8).

Focuses on naming the partitioned parts as unit fractions (1/b) and understanding that the size of the part depends on the total number of parts.

An introduction to identifying and creating equal parts in various shapes, distinguishing between fair and unfair shares in the context of factory production.

A final assessment day where students demonstrate mastery of area concepts including tiling, multiplication, and decomposing rectilinear shapes in the context of a community garden project.

Students apply their knowledge of area to more complex gardening scenarios, including decomposing rectilinear shapes and comparing garden sizes.

In this lesson, students learn to relate tiling to multiplication to find the area of rectangular garden plots. They will count square units and then transition to using side lengths.

A high-energy, St. Patrick's Day themed math game where 4th graders solve multi-step word problems to earn gold coins and reach the end of the rainbow.

A high-energy classroom scavenger hunt where students apply geometry concepts like perimeter and area to real-world objects. Students will measure and calculate dimensions for rectangles, squares, and parallelograms found in their environment.
